Specifications

Troubleshooting

Error 1: When opening the software, the computer prompts "Failed to open the card, please check the card" prompt.

Solution:

1. Check whether the driver of the board is installed, or change the board to a PCI slot.

2. Reinstall the two data cables and check if there is any broken needle.

3. There is a problem with the Weihong card, replace the card.

Error 2: When opening the software, it prompts: three-axis alarm, initialization error signal.

Solution:

1. Check whether the two data lines of the computer and the machine are connected properly.

2. Check whether the fuse of the adapter board in the control box is burned out, and replace the fuse.

3. Check whether the power supply is normal.

Error 3: Misalignment occurs during routing, or the size is wrong.

Solution:

1. Check whether the path of the routing software is correct or not.

2. Check the gap size of the screw rod and whether the fastening screw of the polished rod is loose.

3. Check whether the software parameter settings are correct.

Error 4: When the X-axis moves for a certain period, the Z-axis does not lift the bit, but presses to go up but go down.

Solution:

1. Check whether the Z-axis motor is operating normally, the power and the size of the drive current.

2. Check whether the Z-axis motor cable has poor contact or intermittent disconnection.

3. Check whether the distance of lifting the bit is set.

Error 5: The spindle motor does not rotate or reverses.

Solution:

1. Check the parameter settings of the inverter.

2. Whether the signal wire of the inverter is connected reversely.

Error 6: The phenomenon of smashing the bit appears.

Solution:

1. The power of the Z-axis motor is not enough, and the coupling is loose.

2. The current of the Z-axis driver is too small, or the signal wire is connected incorrectly.

3. The data cable is not connected properly.

Error 7: When opening the software and booting, the axis turns off.

Solution:

1. The problem of the driver or the poor connection of the computer output signal line.

2. The motor wire is in poor contact.

Error 8: The machine is not powered on when it is turned on.

Solution:

Maintenance

CNC router is a precision numerical control machine tool, and the necessary daily maintenance is very important to the service life and accuracy of the machine. Please follow the following requirements for maintenance: 　　

1. When the machine is running, be sure to ensure that the cooling water is clean and the water pump is working properly. Never make the water-cooled spindle motor lack water; replace the cooling water regularly to prevent the water temperature from being too high; if the working environment temperature is too low in winter, you can add antifreeze to the water in the water tank.　　

2. When the machine is working, use the oil pump to add lubricating oil to the oil circuit; every time the machine is used, pay attention to cleaning up, be sure to clean up the dust on the platform and transmission system, and remove the nut on the spindle and the sawdust in the spring tool holder clean up; check the oil circuit system of the machine regularly (weekly) to avoid the machine running unsmoothly due to the blockage of the oil circuit.

(Note: The X, Y, Z axis guide rails are maintained with engine oil; the screw part is added with high-speed butter; if the working environment temperature is too low in winter, the screw and the guide rail (square guide rail or round guide rail) should be washed with gasoline first clean, and then add oil, otherwise it will cause excessive resistance in the transmission part of the machine and cause the machine to displace.)　　

3. When performing maintenance and inspection on electrical appliances, be sure to cut off the power supply, wait until there is no display on the display screen and the main circuit power indicator light goes out before proceeding.

Regularly (weekly) check whether the wiring on the distribution box and the machine is loose, and clean the electrical components such as relays and AC contactors with higher switching frequency. If there is any abnormal operation, repair or replace it in time .
